<p><b>OBJECTIVE</b>To Evaluate four kits for screening HIV antibody by comparing and analyzing the HIV antibody screening positive results and Western Blot (WB) test results.</p><p><b>METHODS</b>From January 2004 to June 2009, three ELISA kits (Zhongshan, Biomérieux and Livzon) were used for initial screening HIV antibody. The reactive positive samples were reexamed by initial ELISA kit and a rapid kit (Abbot Determine HIV-1/2). All repeatedly reactive positive screening results were followed by WB test.</p><p><b>RESULTS</b>A total of 193 (0.094%) WB confirmed positive results were obtained from 206 151 specimens. The sensitivities and predictive values of negative test result (PVN) of three ELISA kits were all 100% and those of Abbot Determine HIV-1/2 were 93.93%, and 91.67% respectively. All false negative results from Abbot were WB indeterminate. The specificities of Zhongshan, Biomérieux, Livzon and Abbot were 99.88%, 99.89%, 99.96% and 89.38%; the study predictive values of a positive test result (PVP) were 35.58%, 46.46%, 76.61% and 92.20%; the efficiencies were 99.88%, 99.89%, 99.96% and 91.98%; the areas under ROC curve of the three ELISA kits were 0.93, 0.99, and 0.95 respectively. PVP of Livzon was obviously higher than those of Zhongshan (chi(2) = 45.804, P = 0.000), Biomérieux (chi(2) = 25.231, P = 0.000) and Biomérieux was higher than Zhongshan (chi(2) = 2.488, P = 0.115). PVP of Abbot was highest (chi(2) = 18.633, P = 0.000, vs Livzon). There were some specimens with S/CO (optical density of sample/cut off) ratio < 6 or > or = 6 in all three groups with positive, indeterminate and negative WB results. The S/CO ratio from Zhongshan in confirmed positive group (14.29 + or - 2.63) was higher than in positive-negative group (2.80 + or - 3.25) (t = 17.652, P = 0.000). The S/CO ratio from Biomérieux in confirmed positive group(16.09 + or - 2.35) was higher than in positive-negative group (2.14 + or - 1.91) (t = 31.622, P = 0.000). The S/CO ratio from Livzon in confirmed positive group (11.54 + or - 1.95) was higher than in positive-indeterminate group (5.54 + or - 3.57) (t = 6.386, P = 0.000), positive-negative group (3.25 + or - 2.41) (t = 21.772, P = 0.000) and positive-indeterminate group was higher than positive-negative group (t = 2.301, P = 0.033).</p><p><b>CONCLUSION</b>The performances of four HIV antibody screening kits are good but estimating WB confirming result in line with S/CO ratio is not available. All repeated screening positive results should be followed by confirmatory tests.</p>

Recently, minocycline has been reported to protect neurologic function evidently by decreasing apoptosis.OBJECTIVE:To study the effect of minocycline on apoptosis and expression of related factor, and protective effect of minocycline on neurologic function of injured spine after spinal cord injury (SCI) in rats.DESIGN: A randomized controlled animal study.SETTING: Tongji Hospital Affiliated to Tongji Medical College,Huazhong University of Science and Technology.MATERIALS: The experiment was performed at the Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology between November 2003 and December 2004. A total of 36male SD rats were divided into four groups: ①Blank control group (group A) with 6 rats, ②injured group (group B) with 10 rats, ③minocycline treatment group (group C) with 10 rats, and ④methylprednisolone treatment group (group D) with 10 rats.METHODS: The animal SCI model was established. Spinal cords of rats in the group A were exposed without injury. Spines of rats in the group B were injured without treatment. Rats of group C was treated with minocycline (50 mg/kg) by intraperitoneal injection at 1 hour after injury, and 24 hours later another 50 mg/kg was given, and then another 25 mg/kg was injected for 5 days. Methylprednisolone (100 mg/kg) was intraperitoneally injected 1 hour after injury in the group D. The rats in the group A and the group B were treated with saline, and the method of administration was the same with that of the group C.MAIN OUTCOME MEASURES: ①Neurofunction evaluation of rats in each group. ②Expressions of Bcl-2 family members (Bcl-2, Bcl-xl, and Bax) were tested with immunocytochemical method. ③Apoptosis index of spinal tissue of rats of each group.RESULTS: A total of 36 rats were involved in the result analysis. ①Neurofunction of rats in the group C increased as compared with the group B (P ＜ 0.05), and there was insignificant difference between group C and the group D (P ＞ 0.05). ②Bcl-2 positive expressive cells in the group C was more than that in the group B, and showed obvious difference between the two groups [(62.53±7.76)%, (35.14±3.70)%,P ＜ 0.05]. There was insignificant difference between expressions of Bcl-xl and Bax in group C as compared with the group B (P ＞ 0.05). ③The number of apoptosis positive cells in the group B was more than that in the group C and D [(44.63± 5.90)%, (32.71± 5.26)%, (34.31± 6.84)%,P ＜ 0.05].CONCLUSION: Minocycline can up-regulate the expression of Bcl-2, and raise the ratio of Bcl-2/Bax, so as to inhibit the neural apoptosis of spine,which have protective effect on neurologic function of injured spine.
RESUMO
Objective: To investigate the changes of gene expression in CD34+ hematopoietic stem and progenitor cells (HSPCs) under different growth environments. Methods: Umbilical cord blood mononuclear cells (UCB MNCs) were cultured in static and stirred systems. After 7 days of culture, CD34+ cells were isolated and total RNA was extracted. Gene expression patterns of CD34+ cells from fresh, static and stirred cultures were compared using differential display (DD). Results: 30 gene fragments displayed differential expression levels based on the conditions of DD. One of differentially expressed genes was identified as RAN, which is a member of oncogene RAS family. This gene may be associated with proliferation of hematopoietic cells. Conclusion: Different growth environments induced differential gene expression patterns of CD34+ HSPCs. These differentially expressed genes would give new insights into optimizing in vitro environments for expanding hematopoietic cells.
